What is the issue you are experiencing?

I just want to be clear from the start, the issue isn't with the ingredient parsing per se, but with the auto-evaluation of the results.
After parsing the ingredients of a recipe, the parser will display the results and some percentages representing how accurate the results are.
Sometimes, these percentages are correct, other times... not so much.

Here's an example:

As we can see from the image, the recipe has 4 ingredient (they're in Romanian, but that shouldn't be a problem in understanding the issue):

• 100 g orez alb
• 300 g apa
• 100g somon
• 1 ou de gaina

After parsing the ingredients, the results are as follows:
100 gram
100 --> detected successfully
gram --> detected successfully
orez alb --> not detected (I didn't have it my database, so this is expected behavior)
What I expect: You got 2 out of 3, so I would expect 66%.
What the parser says: 55%.
Why are you selling yourself short, parser? You got most of it right.

300 gram apa
300 --> detected successfully
gram --> detected successfully
apa --> detected successfully
What I expect: You got them all right, so I would expect 100%.
What the parser says: 51%.
Why are mean 51%, parser? You got it completely right! If that's not 100% right, I don't know what is.

100 gram somon
100 --> detected successfully
gram --> detected successfully
somon --> detected successfully
What I expect: You got them all right, so I would expect 100%.
What the parser says: 64%.
Again, why are you being so hard on yourself, parser? You got it completely right!

1 ou de gaina
1 --> detected successfully
ou de gaina --> not detected (I didn't have it my database, so this is expected behavior)
What I expect: You got 1 (literally). No unit of measure, so that's 50% at best.
What the parser says: 91%.
Now you're just being overconfident! :))

Steps to Reproduce

1. Create a recipe with ingredients.
2. Enable "Ingredient amounts" from Settings
3. Click on Parse
4. Notice the percentages (on the right of each detected ingredient).

Expected result:
The percentages should reflect the success of the parsing process.
Examples:
If 2 out of 3 elements of an ingredient were detected, that a 66% success rate.
If 1 out of 4 elements of an ingredient, that a 25% success rate.
If 3 out of 3 elements of an ingredient, that a 100% success rate.

Actual result:
Sometimes, the percentages are somewhat inaccurate.

Please provide relevant logs
